"The script turned out so nicely that Karan read it and immediately agreed to make it. I think my script is the reason the film is being made," the debut director told Digital Spy.

"If it was a slightly weaker or duller script I would probably be an AD on Yeh Jawaani Hai Deewani right now."

Nair said that her Bollywood journey had involved a degree of good luck, explaining: "I really feel like I'm super lucky, because I've got what I wanted when I wanted it - which is so rare.

"I finished my studies at Ithaca College, Upstate NY, and worked in NYC doing odd film jobs for a year. Casting extras, reading scripts, taking tapes back and forth,that kind of stuff. Soon, I got tired of it and moved to Mumbai to try and get work in Hindi films.

"Coincidentally, on the exact day I landed in Mumbai, Ayan [Mukerji] emailed me saying he [was] looking for crew for his film, and had heard that I was studying film. I knew him through family connections, but we hadn't spoken for years, so Wake Up Sid happened."

Nair went on to add: "I learnt every single process of filmmaking through that film. Ayan took me everywhere and gave me a lot of responsibility, so I really fast tracked my film learning curve."

She also recounted how she next had the opportunity to work on the Priyanka Chopra movie Saat Khoon Maaf.

"A few months later, I got a call from Vishal Bhardwaj's office. I had moved to Mumbai to work with him, and here was his office calling me," Nair recalled.

"I learnt a lot from Vishal sir. I was the script and continuity supervisor and sat next to him for every shot of the film. His attention to detail, and his love for improvisation are my biggest lessons from him."
